Researchers led by radiologist Dr. Ilya Nasrallah, PhD, of the University of Pennsylvania studied the MRI scans of 454 hypertensive patients who were 50 years or older and completed a brain MRI at baseline and then at four-year follow-up in July 2016. Among the two patient groups, they compared hippocampal volume, measures of Alzheimer s disease regional atrophy, posterior cingulate cerebral blood flow, and mean fractional anisotropy (FA) in the cingulum bundle. There is no consistent or clinically meaningful difference in magnetic resonance imaging biomarkers of Alzheimer s disease between intensive and standard blood pressure treatment, Nasrallah and colleagues wrote. Vascular disease is a common comorbidity and may play a factor in initiating or accelerating hippocampal atrophy and mild cognitive impairment (MCI), characteristic biomarkers of Alzheimer s disease. Some studies have found that treating hypertension may reduce the incidence of Alzheimer s disease, but no clear m
